ROLL-CLEANING DEVICE.

Specification of Letters latent. Patented Oct. 26, 1920.

Application filed July 26, 1919.- Serial No. 813,467.

vention being to provide an improved cleaner which simultaneously cleansa pair of rolls of the type ordinarily employed in sheet metal rolling.I

.A; further object is to provide a device of the character stated withan improved mounting which permits the cleaner to be movedlongitudinally of the rolls and which permits any desired pressure to behad against the rolls during the cleaning operation.

A further object is to provide an improved mounting for the cleanerwhich consists of a hanger located below the sheet supporting plateadjustable longitudinally relative thereto 'and having an improvedmounting for a laterally movable carrier to which a cleaning device ispivotally connected and operated by a lever to move the cleaning deviceinto or out of engagement with the rolls and exert the desired pressureduring the 'operation of cleaning.

A further object is to provide an improved mounting for the device whichenables the same to be moved into and out of operative position and forma part of the rolling mill construction in convenient position for useas occasion may require.

With these and other objects in view the invention consists in certainnovel featuresof construction, and combinations and arrangements ofparts, as will be more fully hereinafter described and pointed out inthe claims.

In the accompanying drawings Figure 1 is a plan view with portionsbroken away to illustrate the carrier 5 and the cleaning tool 9; I

Fig. 2 is a View in longitudinal sectio on the line 2--2 of Fig. '1,showing the cleaning device in operation;

Fig. 3 is a view in transverse section on J the .line 3-3 of Fig. 2; and

Fig. 4 is a View similar to Fig. 2, showing the cleaning device lowered.

A represents a supporting base] on which standards 1, 1 are secured andsupport the improved cleaning device. The rolls 2, 2 may have anyapproved mounting, such as is common in rolling mills, and I haveillustrated the ordinary form of standard 2', affording a mounting forthe rolls.

The improved cleaning device comprises, in the main, a work supportingplate 3 mounted upon a hanger 4, which latter sup ports a transverselymovable carrier 5 having a pivoted bracket 6 at its forward end moved bya lever 7 pivoted to the carrier,

as shown at 7 and connected by a link 8 with the bracket 6 so as tocausethe movement of a cleaning block 9 toward and away from the rolls2, all of which will be more fully hereinafterdescribed.

The device is provided with a relatively fiat plate 3 havinglongitudinal dove-tailed grooves 12 therein receiving dove-tailedflanges on the hanger; 4 and permitting longitudinal movement of theplate on the hanger. This longitudinal movement is effected by means ofa screw threaded rod 14 supported in a bearing 15 on'the hanger 4 andengaging a screw threaded sleeve 16 on the plate 3. The outer end ofthe. rod 14: is made. angular, as shown at 17, tore ceive a wrench orother suitable tool to turn the same. The central portion of plate 3 isrecessed, as shown at 3', to provide ample space for the adjusting rod14 and cooperating parts.

The hanger 4 at its rear portion is made with a downwardly and forwardlyprojecting extension 18 having trunnions 10 at its ends mounted ingrooves 11 in the inner faces of standards 1, the trunnions normallyresting in the lower ends of the grooves which form bearings therefor.

The extension 18 has. at its forward edge vertically and horizontallypositioned tracks 19 and 20. respectively, the former receiving a roller21 and the latter a pair of rollers 22 on the carrier 5. The carrier .5is also provided with another roller 23 of a wedge 32 and hook-shapedpins 33 engaging the wedge and driven into perforated lugs 34 on thebracket 6 so that the cleaning block can be removed and replaced asoccasion may require. A

A coiled spring 35 connects the bracket 6 with the carrier 5 and ismainly within a housing recess 36' in the end of the carrier. Thisspring 35 holds the bracket in its normal elevated position, while thedownward movement of the bracket to press the cleaning tool 9 againstthe roll 2 is accomplished by moving the lever 7. This lever 7 is provided with a removable handle 30 to provide the necessary leverage.

. The work supporting plate 3 at its rear end supports a work guidingroller 37 which latter has trunnions 38 at its ends supported inrecessed .bearings 39, as shown most clearly in Fig. 1. The standards 2'are made with supporting shoulders 40 which 'are.

adapted to support the hanger 4: in its lowered position, as indicatedin Fig. 4.

T would'call attention to the shape of the grooves 11 in standards 1.These grooves extend forwardly and downwardly in a straight line andthen at a difi'erent angle so that the movement of the trunnions in thegrooves permits initially an upward move-,

ment with 'a slight rearward tendency and then a greater rearwardmovement which is desirable to bring the device from the position shownin Fig. 2 to that in Fig. 4:, and vice versa.

' The operation is as follows: Assuming the parts will be in' theposition shown in Fig. 2, the o erator pressesdownwardly upon the freeen. of the lever 30, which lever, through the medium of link 8 and arm28, causes the cleaning tool 9 to be pressed against both of the rolls2, 2. As certain portions of the rolls are cleaned, the carrier is movedtransversely, supported and guided in such movement by the rollers 21,22 and 23 until the entire surface pf'both rolls is thoroughly cleaned.To shift the position of the parts so that they will be in the positionshown in Fig. 4, it is necessary to elevate the rear portion of thedevice with the trunnions 10 riding in the grooves 11 when the forwardend of the device can be lowered with the plate 3 resting on theshoulders a0 and the trun nions are in the lower ends of the grooves 11.In this last-named position the lower roll could be cleaned if desired.

Various slight changes maybe made in the general form and arrangement ofparts described without departing from the. inven tion, and hence T donot it myself to the earner operatively connecting said member with thebracket to turn said bracket on said pivot. 2. A device of. thecharacter described, comprising a support, a, hanger pivotally mountedin the support, a wheeled carrier on the hanger, a bracket pivotallyconnected to the carrier, a cleaning tool on the bracket, a
